The 3H-2000PS Series—designed for today’s laboratory
• Affordably-priced—perfect for any laboratory.
• Space saving—each unit takes up less bench space than an open 3-ring binder.
• Versatile—a wide range of characterization techniques for powdered and porous materials.
• Flexible operation—analysis type independent for each station (BET and/or pore size measurement).
•Prepare two samples by vacuum or flow methods simultaneously with sample analysis—at different temperatures if required.
• Access degasser during analysis to start/stop flow or vacuum degassingwith Analysis Interrupt.
•Eliminate cell calibration with classical helium-void-volume mode.
• Upgradeable—can adapt to meet your expanding or changing laboratory needs.
Unique Features
1. Unique and Innovative mainifold gas control system
2. Use of air control valve to avoid the heat effect of electromagnetic valve
3. Two independent vacuum systems permit simultaneous preparation of two samples while analyzing another.
4. Unique sample pretreatment anti pollution device, effectively prevent powder into the degas and analysis system
5. Long duration dewar provides virtually 70 hours analysis capability
